1956 Map of Lake Eleanor

USGS Topo · Published 1972

About this map

The High Sierra water system dominates this mid-century landscape, centered on the Hetch Hetchy Reservoir and Lake Eleanor. Following the 1956 field check, the map illustrates the massive engineering of the O'Shaughnessy Dam and the Hetch Hetchy Aqueduct snaking through the Stanislaus National Forest. Beyond the civil works, the land preserves a record of mountain habitation at Meyers Ranch, Hodgdon Ranch, and the Hazel Green Ranch near the Tuolumne-Mariposa line.
